House extensions in East Finchley, tested against two councils

An extension in East Finchley has to meet terraced and semi-detached houses that share party walls, and sometimes a view toward the Grade II station by Holden and Bucknell. Barnet’s Area 12 appraisal for Deansway and Edmunds Walk records new building by the station intruding on those rooflines. A taller rear addition just outside the Suburb can still show above those rooftops. We survey the rear wall, levels and neighbouring ridges before a massing is drawn.

Two addresses a short walk apart can answer to different planning departments. We confirm the council for the exact address with the GOV. UK local council finder before any drawing is prepared. Inside the Suburb, the Article 4 direction can bring porches and hard standings under control. On Fortis Green, designated in 1974, we ask the council whether further controls apply. Building Regulations approval and party wall notices remain separate in both boroughs.

Skips, scaffold and parking permits are sought from the authority that runs the street. Barnet and Haringey each have their own process, and a red-route frontage follows TfL’s rules instead. Front gardens, paths and boundary walls are protected before the first delivery. Neighbours on both sides of a shared wall hear in advance when the noisiest stages are due. Materials come in planned loads rather than occupying the kerb all day.

Start with the full East Finchley address, the council the finder returns, and photographs of the rear garden and any view toward the station. Add past planning decisions from whichever authority holds them. Hampstead Renovations then agrees a written scope covering survey, consents, structure and making good. Our own teams build the extension in-house, and the completion file names the council that decided each consent.
